[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figure 1-5 An ice storage coil box in the present application includes a box body 1, a reserved opening 13 is opened at the upper end of the box body 1, a recess 14 is provided at the reserved opening 13, the recess 14 is higher than the bottom of the reserved opening 13, but lower than the upper end surface of the box body 1, and a cover plate 2 is detachably provided at the reserved opening 13;

[0023] See also Figure 6-7The cover plate 2 includes a plug plate extending transversely, and the cover plate 2 is inserted into the reserved opening 13 to hold itself. A slot 11 is provided in the reserved opening 13, and the slot 11 is adapted to fit the plug plate 21 so that the plug plate 21 can be partially inserted to hold the cover plate 2 and cover and shield the electrical components in the reserved opening 13;

[0024] A longitudinally extending convex portion 22 is provided at one end of the plug board 21. In order to facilitate the insertion of the plug board 21, the area of ​​the reserved opening 13 is increased by providing the concave portion 14, so that the cover plate 2 can be easily accommodated in the reserved opening 13 before insertion. After the cover plate 2 is inserted into a part of the slot 11, since there is no electrical component in the concave portion 14, it does not affect the cover plate 2 covering the electrical components. The convex portion 22 plays a role in supporting the plug board 21 and maintaining the overall level of the cover plate 2. A locking groove is provided on the plug board 21, and two clamping rods 24 are fixed between the side walls of the locking groove, and a locking ring 23 is sleeved on the two clamping rods 24;

[0025] A locking rod 12 is connected between the side walls of the reserved opening 13.

[0026] See also Figure 7-8 The distance between one card rod 24 and the inner wall of the lock groove is smaller than the distance between the other card rod 24 and the other inner wall, so that when the cover plate 2 is inserted into the reserved opening 13 and the lock ring 23 abuts against the lock rod 24, the lock ring 23 has space to rotate upward to avoid, and when the cover plate 2 is pulled out and the lock rod 24 abuts against the lock ring 23, the lock ring 23 abuts against the inner wall of the lock groove and cannot rotate to avoid.

[0027] The device is provided with two clamping rods 24 in the lock groove, and the distances between the two clamping rods 24 and the inner wall of the lock groove are large and small. The distance between the clamping rod 24 closer to the insertion direction of the cover plate 2 and the inner wall of the lock groove is much smaller than the distance between the clamping rod 24 at the other end and the other inner wall. In this way, when the cover plate 2 is inserted, the lock rod 12 touches the lock ring 23, and the lock ring 23 will have a space to avoid. After the cover plate 2 is inserted, the lock rod 12 moves to the other side of the lock ring 23. At this time, since the distance between the clamping rod 24 and the inner wall of the lock groove is narrow, and the lock ring 23 is sleeved outside the clamping rod 24, the above distance can only accommodate the thickness of the lock ring 23 itself. Therefore, the lock ring 23 has no space to avoid and cannot be pulled out of the cover plate 2, thus completing the assembly of the cover plate 2. When it is necessary to remove the cover 2, the locking ring 23 is pulled upwards, and the clamping rod 24 no longer blocks the removal path of the cover 2 and the locking ring 23 thereon, and the cover 2 can be removed normally. Since the locking ring 23 is affected by gravity during use, it should always remain in a drooping state and will not be subjected to upward stress. Therefore, the locking ring 23 will not move up and cause the cover 2 to be removed. Even if special circumstances cause the locking ring 23 to move up briefly, it is necessary to pull out the cover 2 while the locking ring 23 moves up, that is, to apply a lateral pulling force. This situation does not exist in normal use. Therefore, the above-mentioned locking structure is sufficient to meet the normal working requirements of the cover 2 to cover the reserved opening. The device does not require additional tools during disassembly and assembly, making disassembly and assembly more convenient and quick.

[0028] Furthermore, a dustproof plate (not shown in the figure) is provided on the upper end surface of the box body 1 , and the dustproof plate is placed above the reserved opening 13 and can fit with the locking ring 23 on the cover plate 2 .

[0029] The device is provided with a dustproof plate, which can cover the cover plate 2 to play a dustproof role. Since the dustproof plate is sliding and pushing and pulling, it is located above the cover plate 2 and can press the lock ring 23 to further prevent the lock ring 23 from moving up and increase the stability of the cover plate 2. Since the lock ring 23 is a circular ring and the contact surface is irregular, the dustproof plate is preferably made of a flexible material to increase the adaptability of the contact surface with the lock ring 23.

[0030] Furthermore, anti-slip grooves are provided on the locking ring 23 and the clamping rod 24 .

[0031] The device increases the stability of the lock ring 23 and the lock rod 12 when they are in contact by providing anti-skid patterns, thereby preventing slipping and causing failure to lock or unlock normally.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
